Cell Cycle Regulation Normal Cell Cycle Cellular Reproduction Cell Cycle Regulation Normal Cell Cycle Different cyclin/CDK combinations signal cell activities, including DNA replication, protein synthesis, and nuclear division throughout the cell cycle.

Quality Control Checkpoints Cellular Reproduction Cell Cycle Regulation Quality Control Checkpoints The cell cycle has built-in checkpoints that monitor the cycle and can stop it if something goes wrong. Spindle checkpoints also have been identified in mitosis.

Abnormal Cell Cycle: Cancer Cellular Reproduction Cell Cycle Regulation Abnormal Cell Cycle: Cancer Cancer is the uncontrolled growth and division of cells. Cancer cells can kill an organism by crowding out normal cells, resulting in the loss of tissue function.

Cellular Reproduction Cell Cycle Regulation Causes of Cancer The changes that occur in the regulation of cell growth and division of cancer cells are due to mutations. Various environmental factors can affect the occurrence of cancer cells.

Apoptosis Programmed cell death Cellular Reproduction Cell Cycle Regulation Apoptosis Programmed cell death Cells going through apoptosis actually shrink and shrivel in a controlled process.

Cellular Reproduction Cell Cycle Regulation Stem Cells Unspecialized cells that can develop into specialized cells when under the right conditions

Cellular Reproduction Cell Cycle Regulation Embryonic Stem Cells After fertilization, the resulting mass of cells divides repeatedly until there are about 100–150 cells. These cells have not become specialized.

Cellular Reproduction Cell Cycle Regulation Adult Stem Cells Found in various tissues in the body and might be used to maintain and repair the same kind of tissue Less controversial because the adult stem cells can be obtained with the consent of their donor
